This isn't going to do much at all in the grand scheme of things
> They don't have a choice to drive smaller cars?
Most people aren't driving dualies. Usually they're driving sedans. I'd wager, anecdotally, most people cannot afford new, more efficient cars. If they need to get to work to feed their families, and they're strapped for cash, they'll buy an emissions ridden piece of crap just to get there.
People can't hardly live for themselves and you expect them to shoulder all of the burden that the manufacturing and oil industries are causing.
> To not make changes to your own life whilst wanting government to force the same changes on all of society seems pretty hypocritical.
I'd much rather governments ban net-positive carbon emissions by the major offenders entirely and force all further major offenders to shut down, but that doesn't make our government officials rich does it?
